DRS only works well if the car using DRS has enough time to keep it activated… In other words the straight has to be long enough to allow a DRS pass. Dont think melbourne offers too much in that respect. Of course this year if the cars are closely matched in performance then we might see a little more DRS passes.
But the idea of having a single detection point for more than one DRS activation zones is not fair. That just puts the defending driver in a more helpless situation. With the additional rule allowing the defending driver to move away from the racing line only once, this form of DRS only makes the defending driver a sitting duck.
Looks like the FIA are just interested in seeing overtakes being made on the track no matter how silly they look!!
